Plumbers, HVAC technicians, and serious DIYers working on water supply lines, compressed air systems, or fluid-transfer setups need a reliable 1\/2\" BSP male to female extension adapter that threads on cleanly and holds pressure without weeping joints.\u003c\/p\u003e\n\u003cp\u003eEach adapter is machined from 304 stainless steel with a male BSP thread on one end and a female BSP thread on the other, effectively extending your pipe run by a fixed length. Available in six lengths — 32mm (≈1-1\/4\"), 40mm (≈1-9\/16\"), 50mm (≈2\"), 60mm (≈2-3\/8\"), 70mm (≈2-3\/4\"), and 100mm (≈3-15\/16\") — so you can match the exact gap in your installation. Thread size is 1\/2\" BSP (DN15), sold individually (1 pcs per order).\u003c\/p\u003e\n\u003cp\u003eTypical use cases include extending water supply drop lines behind walls, repositioning pressure gauges and ball valves in tight mechanical rooms, and adding clearance for insulation wrap on stainless steel pipe fittings for plumbing systems.
